This page shows how to change the DNS settings on the TP-Link TL-WR720N router.
When you connect a router to the Internet it gets a few settings from your ISP automatically. One of the settings that the ISP sets in your router is the DNS setting. DNS stands for Domain Name System and it is used to convert Internet names into actual IP addresses. For instance, when you go to "google.com", your are really connecting to an IP address that is mapped through DNS to a number such as:
This mapping happens automatically every time you visit any page on the Internet.
Some ISPs choose to abuse the DNS system and map unknown names to servers that they control. This can be done in a way that you don't know it is happening since your router is getting its DNS settings from your ISP. For instance, if you have one of these ISPs who is hijacking your DNS, and you try to surf the web to "some-random-site.com" and "some-random-site.com" does not exist, you might get a page back from your ISP with local advertisements on it.
By changing your DNS setting in your router you will effectively change the DNS setting for every computer on your network. This is because when a device is connected to your network your router automatically hands out its own DNS settings to that device. This way you can protect your entire network from ISP hijacking with just one setting.
When you change the DNS settings in your router, you usually have to enter a Primary and a Secondary setting. The secondary is only used if the primary can not be located. Here are common settings:
If you want to use Google Public DNS, use the following settings:
If you want to use OpenDNS, use the following settings:
To get started configuring the TP-Link TL-WR720N DNS page you need to login to your router. If you are already logged in you can skip this step.
To login to the TP-Link TL-WR720N, follow our TP-Link TL-WR720N Login Guide.
If you followed our login guide above then you should see this screen.
You begin on the Status page of the TP-Link TL-WR720N. When you have decided to change the Domain Name System settings, click the link on the left side of the page labeled DHCP, then under that, DHCP Settings.
This router has a LAN side DNS server that deals with your day to day internet usage, and the WAN side DNS server that deals with updates.
The page you see above is the LAN side DNS server, change this one by entering the primary address of the DNS Server you picked, in the box labeled Primary DNS. Under that, in the box labeled Secondary DNS, enter the secondary address of the DNS server you want. When you have finished, tick the Save button.
The next page that you will go to is the WAN side DNS server. We recommend setting both, because all routers are a little different and this ensures that you have full control of your DNS server. Click the choice on the left side of the page labeled Network, then below that WAN.
On this new page, first place a check in the box labeled Use These DNS Servers. Then, under that is the Primary DNS space. In this box, enter the same primary address of the DNS server you used on the DHCP page. Below that is the Secondary DNS box, again enter the same secondary address that you used on the previous page.
You did it, click Save and you're finished.
Most devices on your network will not begin using the new DNS settings until they have been rebooted. After rebooting a device you can go to it's network settings and verify that it is using the DNS servers that you specified.
